Ameera: Latest Analyses
Ameera showed results on three separate datasets: Carsten's data (nicotine vs placebo), Karen and Simon's data (drug users) and Jonathan Power's data (children). the last two datasets can be found in the fMRI/Benchmark data section of this wiki.
Ameera's slides can be found at: [[1]] In a nutshell, she has now finished coding up all of the diagnostics in the Power paper and has run these codes on the benchmark data provided by Simon. Curiously (and contrary to Simon), she found no distance-related effects of motion. The discrepancy may be in her scripts or it may be the different preprocessing she used - she will be investigating this issue.
Ameera has also circulated (by email) a document about what she has learnt regarding the methods of the Power et al NeuroImage paper over the course of here email exchanges with Jonathan Power.
Mika has also circulated (by email) the preprint of Satterswaithe's paper in press at NeuroImage on motion and optimal preprocessing.
Tiago: The issue of lag
Tiago's slides will soon be available here.
Outcomes
We are please that the motion task force seems to have successfully dealt with the motion-related issues highlighted by recent papers such as Power et al 2012. The task-force is now dissolved, and the next steps will be as follows:
- Ameera will release a Beta version of her diagnostics toolbox (hopefully within the next week)
- The new BMU preprocessing pipeline will be distributed (over the next couple of months).
- We will have a joint meeting with the CBU, CamCAN and any other interested parties to disseminate these results in the first week of September. We will also set up a website and all relevant documentation for these packages by that time.
